The lock illustrated is arse called tubular lock, which maybgslipped into a round hole'in the edge of thed'oor. I Such locks in general are Well known. The lock illustrated includes a lock case 5 and a lock case cover 6, which may be held together, as by means of the lug onthe cover fitting into a notch 8 in the lock case and by means of a single screw 9 at the opposite end.

The shank or dogging spindle 24 passes-through an aperturein' the door and is preferably journaled in an aperture 26 in the I A thumb piece 28 is attached, 1

to the spindle 24 at the outside ofthe rosette and beneath the knob.

When'the thumb piece ZBis turned so as to' 50 position the dogging lug 19 as shown in Fig. 3 it will be clear that such dogging lug I9 will lie directly behind the upstanding lug I3 on the latch 5 'slide l4, which normally retracts the latch bolt. The, lug .I3 is of course wide enough to engage" both lever l2 and lug l9 which are arranged side sition whenlthelatqhgbolt isjnoved a), retracted by side. With the lug l9 positioned neither knob can be turned, since the latch slide M cannot be retracted. 'When the dogging lug I9 is moved to its out-of-the-way position, as shown in Fig. 2, the latch bolt may be retracted in a normal manner by means of the latch slide, as will be understood.

It will be noted that the latch bolt itself is not dogged in the illustrative lock shown and therefore is free to move to retracted position regardless of the position of the dogging lug l9.

By our. improved arrangement the mere act of slamming thedoor, with consequent retraction of the latch, will throw the dogging means to inoperative position, so that even if the dogging and modifications may be made within the scope Therefore, if a person should inadvertently turn the thumb piece so as to move the dogging lug into operative position, as shown in Fig. 3, while the door is open, both knobs will be locked against rotation. locking himself out we have provided means for In order to prevent a person from.

position, as when the door slams. In the form shown the dogging member has the retracting lug positioned in'the path of the upstanding lug H on the latch bolt, so that when the latch bolt I0 is moved to retracted position the lug I! will engage theretractinglug 20 on the doggingmemher and move the dogginglug I9 to its inoperative "position; for example, as shown in Big. 2.

In the event that the retracting movement of thela'tch bolt H! is not sufficient to move the dogging member to its final inoperative position, operation of one of the knobswill eifectmovement of the dogging member to final inoperative position bythe camming action of the lug 13 on the dogginglug l9.

Ina bathroom: lock or the like it isoften'desirable to provide means to throw the dogging means from the'outside. In thepresent instance thelock caseat'the outside is provided with an aperture 29; and the outside rosette as well as the latch slide [4 is provided with registering recesses. The dogging member hasits angular bore in registry withthose recesses,sot hat an angular, tool may, be inserted from the outside so as to move the dogging memberto inoperative position in case ofem'ergency;

It will'be seen that we have providedexceed+ ingly simple meansfor dogging one or both knobs;

and means which in'no wise interfere with'other parts of the lock. No changes need be made in the knobs or'other parts, other thanthe making of a small hole in oneor possibly both rosettes.

The dogging member. is preferably secured in the cover, so that. there is no possibility ofjits becoming lost or being omitted should thelock be taken apart. The dogging means in the preferred form dogs not only the outsideknobbut alsothe inside knob, so that when the, inside knob is dogged it cannot be turned and the'pe'rson at the inside is sure dogged.
